摘 要: 本文在前人研究基础上,利用岩石地球化学及野外地质学,对白银厂矿田变质火山岩岩石学特征、地质构造、岩浆成矿作用、找矿标志等提出新的认识;重点对折腰山—火焰山矿区的构造变形及其控矿条件和成矿规律等进行了深入分析,提出了成矿模式与找矿思路,对该地区今后的找矿勘探工作具有指导性意义。 Based on the studied results of the previous geological literatures and exploration practices,this paper presents some new opinions on the petrological and structural characteristics,magmatism,mineralization and ore-prospecting indicator of meta-volcanic rocks in Baiyin Mineral Field by the means of igneous geochemistry and field geology.Particularly,it points out the mineralization models and ore-prospecting thoughts in detail,and provides a guide for prospecting exploration in this area through the key analyses of structural deformation,mineralization mechanism and metallogenetic rule of Zheyaoshan-Huoyan deposit.
